Dizzy spells and cramping

Kaylee
Hello I'm 11dpo or 12 and I've been having some cramping and some major dizzy spells.  I've been having some other symptoms as well but these ones have been sticking out to me. Every month I keep tract of all my symptoms and I have never had this much cramping and I've never had dizzy spells. 
I'll be laying down watching tv and then suddenly the whole room is spinning! Has anyone had some intense cramping and dizzy spells and got a bfp
Not knowing what's going on in driving me nuts!
